The Physics of Crumbling a Wall
Started playing with bullet physics, nearly crapped my pants. I made a scene but, I need help in re-working it so that it looks better. The scene is a docking bay where a large asteroid enters through the wall. I want the chunks to be of varying sizes and depths for more realism because when something crashes through, you won't get uniform pieces flying everywhere. So I duplicated the asteroid over and over, then modified the shape of several pieces. I then stacked everything on the wall about to be crunched. Then I keyframed the asteroid to pass through the wall. Physics throws everything around nicely but, it's that initial part where I'd like the wall to be smooth at first, then mangled as the rock rips through it.
I'm trying to ask a question without knowing the terminology -- ! Is there a way to pack the rock pieces inside a smooth shape that then breaks apart? Does that make any sense?
I'm also wondering if I should build interior layer of the wall with small flat uniform blocks (like little panels), then line the jagged pieces directly behind it so that when the asteroid passes through both layers it just scatters everything. Maybe that wouldn't be too bad.
